It's time for the second TV Tropes Halloween Avatar Contest, theme: cute monsters! Details and voting here.
A deleted scene from the original Tintin and the Broken Ear album.
A tube used to shoot darts at targets. Often used by tribesmen. Expect poison
Its near-silence makes it an ideal exotic weapon for an assassin. It's surprisingly common for the user to accidentally inhale the dart. Another regular gag is for the target to grab the end of the gun and blow the dart back

- Ranma uses one to shoot down the Principal's hot air balloon in the manga
- A group of onetime villains in Spider-Man comic (four criminals who learned to copy Vulture's wings) used those. The curare was fatal for humans — Spider Man was too tough to die, but would get stiffer with every dart and actually got close to succumbing. The next issue, he had to save their lives when the real Vulture came to town.
- In one Batman possible future during the Armageddon 2001 series, The Joker frames Batman for the Penguin's murder by having a henchman shoot a poison dart this way, thus making it appear as if Batman knocked Penguin off a side railing with his Batarang and made the villain fall to his death.
- Used by Papa Smurf in The Smurfs comic book story "The Black Smurfs" (and its English version "The Purple Smurfs") to shoot an antidote pellet into an infected Smurfs' mouth.
- Tintin: Used by the Arumbaya Indians in The Broken Ear and Tintin and the Picaros, as well as by the villains in The Cigars Of The Pharao and The Blue Lotus.
- In Apocalypto, Jaguar Paw improvises one with leafs. He creates the darts with thorns and poisons them with frog venom.
- Used in Hudson Hawk (by CIA agents, who should logically have something better), with explicit mention of curare, which is treated as a temporary paralyser. Because it was improperly prepared, the victims recover sooner than anticipated.
- Used in Ace Ventura: When Nature Calls. Ace is shot with dozens of little darts (with hilarious effects) before he passes out.
- Used by the Hovitos in Raiders of the Lost Ark in the opening sequence.
- In Young Sherlock Holmes, an assassin uses a blowgun to shoot darts tipped with a hallucinogenic drug.
- The natives in Aguirre, the Wrath of God keep sniping at the conquistadors on the raft with these.
- Tim Allen's character in Jungle 2 Jungle contrives to shoot himself in the leg with semi-paralytic darts not once but twice. Once was mildly amusing, twice makes you despair for the writers.

- In The Sign Of The Four, Tonga uses poison blow darts.
- In one Forgotten Realms novel, the pirate hunter Captain Deudermont is darted by a thug who wanted to claim the black-market bounty on him. Apparently, his darts are made from cat claws (don't ask how those could be used as darts) and no other ammunition is compatible with his blowgun.
- In Midworld and its sequel, human hunters on the green world use rifle-like blow guns called "snufflers", modeled on distant memories of their colonial ancestors' firearms. They're powered by tank seeds, which contain air bladders that burst when punctured, propelling their toxic-thorn projectiles with great force.

- Warhammer Fantasy has these as a Wargear option for Skinks, and a Huge version for mounting on dinosaurs.
- Dungeons & Dragons: The Unearthed Arcana (1985) supplement introduced the blowgun (which was 4-7 feet long) as an available weapon. The needle did only one Hit Point of damage, and was therefore only effective if poisoned.
- A Traveller magazine article included a Tech level 0 blowgun that cost zero credits, meaning there was no reason not to give your character one. It only dealt nonlethal damage, so like the D&D example was designed for poison.
- Little Big Adventure: Twinsen, the player character, uses one in the second installment.
- Donkey Kong 64: Lanky's Grape Blowgun
- In the second chapter of Eternal Darkness, you receive these. It poisons enemies but does very little damage either way and has limited ammo.

- In Civilization Revolution, one of the barbarian tribes you can encounter has their spokesman threaten you with a blow gun.

- Diablo II has pygmy enemies that uses blow darts to attack.
- The witch-doctor in the third game uses one for their starting ability.
- You can find blowguns in some chests near the surface of Terraria. While getting ammunition for it is a cinch (it uses seeds that you collect by cutting grass), the weapon is far outclassed by most other ranged weapons, at least one of which you should have at that point.
- Blowguns are an option in Dungeon Crawl. They don't do much damage, but are excellent for inflicting status conditions (most commonly poison, but some other Standard Status Effects are also available) from a distance without relying on magic. Curare needles are particularly effective, as they also inflict damage through asphyxiation.
- In Strays, Feral starts putting one together, before the Tag Along Kid botches his assassination job.
